On April 27, 2013, the European Commission announced the initiation of an anti-subsidy investigation on imports of solar glass consisting of tempered soda-lime-flat-glass, with an iron content of less than 300 ppm, a solar transmittance of more than 88 %, a resistanceto heat up to 250 °C, a resistance to thermal shocks of <U+0394> 150 K and having a mechanical strength of 90 N/mm2 or more, from China (Notice No 2013/C 122/17). The products subject to investigation are classified under the following HS code: ex 7007.1980. The complaint was lodged on March 14, 2013 by EU ProSun Glass, on behalf of producers representing more than 25% of the EU production of the subject goods.

On May 13, 2014, the European Commission decided to impose a definitive countervailing duty on imports of solar glass originating in China (Commission Implementing Regulation (EU) No 471/2014). The rate of the duty ranges from 3.2% to 17.1% of the net free-at-Union-frontier price, depending on the company. This definitive duty entered into force on May 15, 2014. Commission Implementing Regulation (EU) No 471/2014 was published in the Official Journal of the European Union (L 142) on May 14, 2014.

On 14 May 2019, the European Commission initiated a sunset review of the countervailing duty imposed on imports of solar glass from China. The investigation follows the application lodged on 13 February 2019 by EU Pro Sun Glass.
